x^{2} - 30 = x

x = 6, x = - 5

Solution steps

x^{2} - 30 = x

Move

x

to the left side

x^{2} - 30 - x = 0

Write in the standard form

a x^{2} + b x + c = 0

x^{2} - x - 30 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 1 ) \pm ( - 1 ) ^{2} - 4 \cdot 1 \cdot ( - 30 )}{2 \cdot 1}

(- 1)^{2} - 4 \cdot 1 \cdot (- 30) = 11

x_{1, 2} = \frac{- ( - 1 ) \pm 11}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- ( - 1 ) + 11}{2 \cdot 1}, x_{2} = \frac{- ( - 1 ) - 11}{2 \cdot 1}

x = \frac{- ( - 1 ) + 11}{2 \cdot 1} : 6

x = \frac{- ( - 1 ) - 11}{2 \cdot 1} : - 5

The solutions to the quadratic equation are:

x = 6, x = - 5

3 (x + 2) < 3 x + 5

7 x^{2} + 2 x = 0

x - 5 < 0

(- \frac{2 x}{3 y}) (- 5 x y)

- 4 x + 14 > 6 and 3 x + 5 > 17
